Question for the Experts

[Kevin MURPHY]

Dear all

 

I recently made some changes to a domains mx record. It use to be, mx =
serverA, which relays clean mail to Exchange Server

Because this domain was really getting hammered, I moved it to a more
powerful spam filtering server.

MX Record is now ServerB, which fwds clean mail to ServerA, which relays it
to the Exchange Server.

 

My Problem now is that some spammers are still sending mail direct to my
ServerA for this Domain.

 

So I am looking at a way to configure the ServerA, so it only excepts mail
for this domain if it comes from server (The more powerful one) So it drops
the spammers on ServerA

 

Thanks

 

Kevin
